Avulsions are most characteristic of aggrading fluvial systems, but along the Klip River, subhumid eastern South Africa, abandonment and re-establishment of meander belts occurs under conditions of negligible vertical ...

Optical dating has been applied to sediments preserved in Little Sippewissett Marsh, Massachusetts, USA, which are associated with overwashing of the beach barrier during hurricane strikes on the coast. The aims were to ...

This paper argues that the concept of the 'pedagogical state' (Hunter 1994, Kaplan 2007) can be employed to better understand the cultural practices of governing through pedagogical means, and the evolving pedagogical ...

Within Australia, the discrimination and mapping of forest communities has traditionally been undertaken at the stand scale using stereo aerial photography. Focusing on mixed species forests in central south-east Queensland, ...

Interglacial fluvial sediment sequences are common in lowland Britain where their palaeontology has been considerably studied but their sedimentology is poorly known. By contrast, Holocene (Flandrian) sequences have yielded ...

High-resolution titanium (Ti) data obtained using an ITRAX XRF core scanner from a laminated sediment core from the Laguna de Juanacatlan, western central Mexico yield a unique high-resolution record of runoff (precipitation) ...

A comparison of a 6450 C-14 yr PO and delta(13)C record of authigenic calcite from Lake Awassa, Ethiopia, with other proxy climate records in the area suggests that the lake records long-term regional climate changes. ...

Lake Ashenge, a closed-basin lake near the northernmost penetration of summer monsoon rains, is well placed to provide a continental record of past changes in the strength of the African monsoon system. Diatom and oxygen ...

East African paleoenvironments are highly variable, marked by extreme fluctuations in moisture availability, which has far-reaching implications for the origin, evolution and dispersal of Homo sapiens in and beyond the ...

Despite the difficulties of establishing formal hydraulic and geometric similarity, small-scale models of drainage basins have often been used to investigate the evolution and dynamics of larger-scale landforms. Historically, ...

The relationship between state administrations and environmental issues has been an enduring concern of geographers, environmentalists, philosophers, sociologists and political scientists for a considerable length of time. ...

Recent geographical contributions to post-colonial studies have paid relatively little attention to subterranean spaces as arenas of modern European imperial and colonial expansion and instead have concentrated almost ...

Ground penetrating radar (GPR) profiles across a complex linear dune in the Namib Sand Sea have been used to image sets of cross-stratification and their bounding surfaces. A combination of radar facies analysis and radar ...

This paper outlines research undertaken to assess the ability of textural information, from image filters, to be used alongside hyperspectral data for the classification of broad forest types. The study made use of 2.6 m ...
